Product Description

The Wilwood 230-4900 Dynamic Front Rotor Bolt Kit is a specialized hardware set designed to securely mount rotors to hats or hubs in performance disc brake systems. This kit includes 12 Grade-8 alloy steel bolts with matching T-nuts that work with dynamic mount rotor designs, allowing the rotor to expand and contract under high temperatures while maintaining tight attachment to the hat or hub. The hex drive heads make installation and service easy with standard tools.

Ideal for race and street applications, the 230-4900 bolts are commonly used with Wilwood rotors and compatible aftermarket hat adapters where a 12 x 1/4-20 bolt pattern is required. Their robust Grade-8 construction and black oxide finish help resist corrosion while providing reliable clamping force for demanding braking conditions. Because this hardware kit fits a variety of rotor and adapter combinations, it does not have specific year/make/model vehicle fitments - compatibility is based on bolt circle and rotor/hub design.
